See e.g. 〕 that is found in Taiwan and in the southern Ryukyu Islands (Japan).〔 ==Taxonomy== There are two subspecies:〔 * ''Achalinus formosanus formosanus'' Boulenger, 1908 — Taiwan * ''Achalinus formosanus chigirai'' Ota and Toyama, 1989 — Ryukyu Islands Specific name ''formosanus'' means "from Formosa", referring to the fact that this species was first described from a specimen from Taiwan.〔 ''chigirai'' refers to Yoshinori Chigira, who collected the first specimen of ''Achalinus formosanus chigirai''.〔 ''Achalinus formosanus formosanus'' is ecologically and morphologically similar to the Taiwan endemic ''Achalinus niger'';〔 the two differ in some scale counts and characteristics.〔 A study using genetic markers found these two taxa to be overlapping, warranting further studies on their taxonomy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Achalinus formosanus」の詳細全文を読む スポンサード リンク
